Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a remote airbag ignition method and device, a computer program, and a readable storage medium. Background Art

[0002] Car side collision is a traffic accident with high frequency and high number of casualties. The side structure of the car is weak and the energy absorption space is insufficient, so the damage caused to the occupants in the car by the side collision is difficult to control. Previous studies have focused on the proximal occupants in the collision, and there are relatively few studies on the distal side collision, which has not received enough attention. Statistics show that the MAIS3+ level injuries of front passengers over 12 years old mainly include secondary collisions between non-collision side occupants and collision side occupants, as well as secondary collisions between non-collision side occupants and interior decorations such as seats. The vehicle seat belts and seats often do not effectively restrain the lateral movement of the dummies. Therefore, it is particularly important to increase the design of configurations such as distal protection airbags to control the degree of occupant deviation. CNCAP (China New Car Assessment Program) 2024 introduces distal occupant protection to evaluate the vehicle safety level, which further promotes the installation of distal airbags in cars.

[0003] However, when the remote airbag is ignited also has a significant impact on the safety of the members. It is necessary to judge the ignition of the remote airbag to reduce the adverse effects of the remote airbag itself on the members. Summary of the invention

[0004] The present application provides a remote airbag ignition method and device, a computer program and a readable storage medium to solve the problem that the current remote airbag ignition moment affects the safety of the occupants.

[0005] In a first aspect, the present application provides a method for igniting a remote airbag in a side collision, which is applied to a vehicle with a remote airbag between a driver and a passenger, and includes the following steps:

[0006] Get the side collision position and collision parameters;

[0007] Determine the deployment strategy of the remote airbag based on the side impact location, collision parameters and passenger seat situation;

[0008] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side impact locations and / or different passenger seat conditions.

[0009] In the present application, whether to deploy the remote airbag is determined based on the side impact position, collision parameters and the passenger's riding condition. That is, the remote airbag and the side airbag are not controlled to be deployed simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on the safety of the occupants.

[0010] In some embodiments, the installation position of the remote airbag includes any one of being installed only on the main driver's side, only on the co-pilot's side, and being installed on both the main driver's side and the co-pilot's side. Different car brands and different models have different remote airbag installation positions due to actual use needs. Different remote airbag detonation strategies can be selected according to the different remote airbag installation positions to provide protection for the main driver and co-pilot members in different situations.

[0011] In some embodiments, the remote airbag detonation strategy includes at least two of detonating the remote airbag and the side airbag simultaneously, not detonating the remote airbag, and detonating the remote airbag after the side airbag. For a certain vehicle model, the installation position of the remote airbag is fixed and unique. Therefore, for a fixed vehicle model, there are at least two different remote airbag detonation strategies according to the side collision position, collision parameters, and the passenger seat situation, so as to provide protection for the main driver and the passenger seat in different situations.

[0012] In some embodiments, the collision parameter includes at least one of the collision acceleration and the door pressure value of the vehicle door, and the collision parameter is used to judge whether the remote airbag detonation parameter threshold is reached. When a collision occurs, on the one hand, the most intuitive change of the vehicle collision is the change in acceleration, and on the other hand, the compression of the occupant by the collision can be reflected by the door pressure value of the vehicle door. At least one of the collision acceleration and the door pressure value of the vehicle door can more realistically reflect the compression and impact felt by the occupant when the collision occurs, thereby improving the judgment accuracy of the remote airbag detonation strategy.

[0013] In some embodiments, if the remote airbag of the side impact vehicle is only arranged on the main driver's side, the strategy of determining the remote airbag detonation according to the side impact position, collision parameters and the passenger's riding condition includes:

[0014] If the side collision position is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously; or,

[0015] If the side collision is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger seat, the remote airbag will not be deployed; or,

[0016] If the side collision position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag will be controlled and then the side airbag will be deployed.

[0017] When the remote airbag of the side-impact vehicle is only set on the main driver's side, if the side impact position is on the co-pilot side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, the driver of the main driver will quickly fall to the co-pilot side under the action of inertia. In order to protect the head of the main driver, the remote airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the co-pilot side, the remote airbag and the side airbag are controlled to be detonated at the same time.

[0018] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the main driver's occupant will not fall to the front passenger side, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the remote airbag, and the main driver can also be protected. At the same time, the use of side airbags is reduced, reducing costs.

[0019] When the distal airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the front passenger seat, under the action of inertia, the front passenger seat occupant will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger seat occupant. While protecting the front passenger seat occupant, it is also necessary to reduce the squeezing of the main driver's seat when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the main driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the distal airbag detonation on the occupants.

[0020] In some embodiments, if the remote airbag of the side-impact vehicle is only arranged on the passenger side, the strategy of determining the remote airbag detonation according to the side-impact position, collision parameters and the passenger seat condition includes:

[0021] If the side collision position is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously; or,

[0022] If the side collision is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag and the side airbag are controlled to deploy simultaneously; or,

[0023] If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger side, the remote airbag will not be deployed.

[0024] When the distal airbag of the side-impact vehicle is only set on the passenger side, the side impact position is on the passenger side, and the threshold of the distal airbag detonation parameter is reached according to the collision parameters, the driver of the main driving seat will quickly fall to the passenger side under the action of inertia. In order to protect the head of the main driving seat occupant, the distal airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the passenger side, the distal airbag and the side airbag are controlled to be detonated at the same time.

[0025] When the distal airbag of a side-impact vehicle is only set on the co-pilot side, the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the co-pilot seat, the co-pilot occupant will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the co-pilot occupant. The distal airbag is only set on the co-pilot side, and its detonation will not affect the main driver's occupant. Therefore, controlling the distal airbag to be set only on the co-pilot side can better protect the co-pilot occupant.

[0026] When the distal airbag of a side-impact vehicle is only set on the co-pilot side, the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is no one in the co-pilot seat, since there is no occupant in the co-pilot seat and the main driver's occupant will not fall towards the co-pilot seat, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to detonate the distal airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0027] In some embodiments, if the remote airbags of the side-impact vehicle are arranged on both the main driver's side and the front passenger's side, the strategy for determining the remote airbag detonation according to the side-impact position, collision parameters and the front passenger's riding condition includes:

[0028] If the side collision position is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously; or,

[0029] If the side collision is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger seat, the remote airbag will not be deployed; or,

[0030] If the side collision position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag will be controlled and then the side airbag will be deployed.

[0031] When the remote airbags of the side-impact vehicle are set on both the main driver's side and the front passenger's side, and the side impact position is on the front passenger's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, the driver of the main driver's seat will quickly fall to the front passenger's side under the action of inertia. In order to protect the head of the main driver's seat, the remote airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the front passenger's seat, the remote airbag and the side airbag are controlled to be detonated at the same time.

[0032] When the remote airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the driver's seat occupants will not fall towards the front passenger seat, the side airbags are sufficient to provide protection for the driver. Therefore, there is no need to detonate the remote airbag, and the driver can also be protected, while reducing the use of side airbags and reducing costs.

[0033] When the distal airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger side, under the action of inertia, the front passenger seat occupant will quickly fall to the driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger seat occupant. While protecting the front passenger, it is also necessary to reduce the squeezing of the driver when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the distal airbag detonation on the occupants.

[0034] In a second aspect, the present application provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application are implemented.

[0035] In a third aspect, the present application provides a computer program product, including a computer program, which, when executed by a processor, implements the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application.

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0046] Car side collision is a traffic accident with high frequency and high number of casualties. The side structure of the car is weak and the energy absorption space is insufficient, so the damage caused to the occupants in the car by the side collision is difficult to control. Previous studies have focused on the proximal occupants in the collision, and there are relatively few studies on the distal side collision, which has not received enough attention. Statistics show that the MAIS3+ level injuries of front passengers over 12 years old mainly include secondary collisions between non-collision side occupants and collision side occupants, as well as secondary collisions between non-collision side occupants and interior decorations such as seats. The vehicle seat belts and seats often do not effectively restrain the lateral movement of the dummies. Therefore, it is particularly important to increase the design of configurations such as distal protection airbags to control the degree of occupant deviation. CNCAP (China New Car Assessment Program) 2024 introduces distal occupant protection to evaluate the vehicle safety level, which further promotes the installation of distal airbags in cars.

[0047] Remote airbags, also known as inner airbags or central airbags, are mainly installed in the area between the front passengers of the vehicle. They can be installed on the main driver's side, the front passenger's side, or both. In the event of a side impact, they can prevent the front passengers' bodies from colliding with each other and causing injuries. Remote airbags usually adopt the design of two large-volume cavities for the head and chest, which can effectively absorb impact energy and provide support, thereby protecting the occupants' heads and upper bodies from serious injuries.

[0048] However, when the remote airbag is ignited also has a significant impact on the safety of the members. It is necessary to judge the ignition of the remote airbag to reduce the adverse effects of the remote airbag itself on the members.

[0049] In view of this, the present application provides a remote airbag ignition method and device, a computer program and a readable storage medium to solve the problem that the existing remote airbag ignition moment affects the safety of the occupants.

[0050] First, as Figure 1 As shown, in the first embodiment of the present application, the present application provides a remote airbag ignition method in a side collision, which is applied to a vehicle with a remote airbag between the main driver and the co-driver, comprising the following steps:

[0051] S10, obtaining the side collision position and collision parameters;

[0052] S20, determining a remote airbag detonation strategy according to the side impact position, collision parameters, and passenger seat condition;

[0053] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side impact locations and / or different passenger seat conditions.

[0054] In the present application, whether to deploy the remote airbag is determined based on the side impact position, collision parameters and the passenger's riding condition. That is, the remote airbag and the side airbag are not controlled to be deployed simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on the safety of the occupants.

[0055] It should be noted that the driver's side and the co-pilot side of the vehicle can be selected according to the regulations of the actual place of use. For example, in some areas, the main driver's side is on the left side of the vehicle's driving direction, and the co-pilot side is on the right side of the vehicle's driving direction. In some areas, the main driver's side is on the right side of the vehicle's driving direction, and the co-pilot side is on the left side of the vehicle's driving direction.

[0056] It should be noted that the collision position is determined according to the direction of the vehicle's lateral acceleration during a side collision. That is, no matter whether the collision occurs at the front, body or rear of the vehicle, as long as the acceleration direction measured by the acceleration sensor is used, it can be determined whether the collision position is on the main driver's side or the co-driver's side. If the vehicle's lateral acceleration direction is toward the main driver's side, the collision position occurs on the co-driver's side; if the vehicle's lateral acceleration direction is toward the co-driver's side, the collision position occurs on the main driver's side. It should be noted that the vehicle's lateral acceleration takes a positive value. Judging the collision position by the direction of acceleration is more sensitive and concise. It should be noted that since the collision acceleration needs to reflect the force applied to the occupants during the collision, the acceleration sensor is usually located at the occupant's seat position so that the measured acceleration is more consistent with the member's feelings.

[0057] In actual operation, the acceleration sensors on the main driver's side and the co-driver's side can be used to detect the side where the collision occurs, and the side whose acceleration reaches the preset value first within a set time, for example, within 20ms. This is because when a collision occurs, it takes a certain amount of time for the acceleration to be transmitted from the collision side to the non-collision side. Therefore, the acceleration sensor on the collision side will detect the signal before the acceleration sensor on the non-collision side, and will also detect that the acceleration reaches the preset value before the acceleration sensor on the non-collision side.

[0058] In combination with the first aspect, in the second embodiment provided by the present application, the installation position of the remote airbag includes any one of being only installed on the main driver's side, only installed on the co-pilot's side, and being installed on both the main driver's side and the co-pilot's side. Different car brands and different models have different remote airbag installation positions due to actual use needs. Different remote airbag detonation strategies can be selected according to the different remote airbag installation positions to provide protection for the main driver and co-pilot members in different situations.

[0059] In combination with the first aspect, in the third embodiment provided in the present application, the detonation strategy of the remote airbag includes at least two of detonating the remote airbag and the side airbag at the same time, not detonating the remote airbag, and detonating the remote airbag after the side airbag. For a certain vehicle model, the installation position of the remote airbag is fixed and unique. Therefore, for a fixed vehicle model, there are at least two different remote airbag detonation strategies according to the side collision position, collision parameters and the passenger seat situation, so as to provide protection for the main driver and the passenger seat in different situations. It should be noted that the side airbag in the present application refers to the outer side airbag. Specifically, the side airbag on the main driver's side refers to the side airbag on the main driver's side away from the passenger seat; the side airbag on the passenger seat refers to the side airbag on the passenger seat away from the main driver's side. It should be noted that the detonation of the airbag brings about the release of energy. When the collision intensity of the car is low, the detonation of the airbag brings greater risks than the collision of the car.

[0060] In combination with the first aspect, in a fourth embodiment provided by the present application, the collision parameter includes at least one of the collision acceleration and the door pressure value of the vehicle door, and the collision parameter is used to judge whether the remote airbag detonation parameter threshold is reached. When a collision occurs, on the one hand, the most intuitive change in a vehicle collision is the change in acceleration, and on the other hand, the compression of the occupant by the collision can be reflected by the door pressure value of the vehicle door. At least one of the collision acceleration and the door pressure value of the vehicle door can more realistically reflect the compression and impact felt by the occupant when the collision occurs, thereby improving the judgment accuracy of the remote airbag detonation strategy.

[0061] By judging whether the collision acceleration reaches the collision acceleration threshold of the remote airbag detonation, it is possible to identify whether the intensity of the collision reaches the degree that requires the remote airbag to be detonated, and the judgment accuracy of the remote airbag detonation strategy can be improved. It should be noted that the collision acceleration threshold of the remote airbag detonation can be the detection of 5 to 10 acceleration peaks of gravity acceleration within 10ms of the collision, which is a prerequisite for the airbag detonation, that is, the airbag detonation parameter threshold. In some embodiments of the present application, the judgment accuracy of the remote airbag detonation strategy can be improved by first judging whether the collision acceleration reaches the collision acceleration threshold of the remote airbag detonation, and then judging whether the door pressure values ​​of the doors before and after the collision reach the door pressure threshold of the remote airbag detonation. It should be noted that the door pressure threshold of the remote airbag detonation can be in the range of 10 to 14 kPa, that is, after the collision, according to different vehicle models, as long as the detected door pressure value reaches the pressure value set in 10 to 14 kPa, it is judged that the detonation condition of the remote airbag is reached.

[0062] Combined with the first aspect, Figure 2 As shown, in the fifth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the main driver's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the passenger's riding condition includes:

[0063] S201. If the side collision position is on the passenger side and it is determined based on the collision parameters that the remote airbag deployment parameter threshold is reached, the remote airbag and the side airbag are controlled to be deployed simultaneously.

[0064] When the remote airbag of the side-impact vehicle is only set on the main driver's side, if the side impact position is on the co-pilot side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, the driver of the main driver will quickly fall to the co-pilot side under the action of inertia. In order to protect the head of the main driver, the remote airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the co-pilot side, the remote airbag and the side airbag are controlled to be detonated at the same time.

[0065] Combined with the first aspect, Figure 3 As shown, in the sixth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the main driver's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the passenger's riding condition includes:

[0066] S201. If the side collision position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger seat, the remote airbag is controlled not to be deployed.

[0067] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the main driver's occupant will not fall to the front passenger side, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the remote airbag, and the main driver can also be protected. At the same time, the use of side airbags is reduced, reducing costs.

[0068] Combined with the first aspect, Figure 4 As shown, in the seventh embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the main driver's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the passenger's riding condition includes:

[0069] S201. If the side collision position is on the main driver's side, and it is judged based on the collision parameters that the remote airbag deployment parameter threshold is reached, and there is someone sitting on the front passenger seat, the remote airbag is controlled to deploy after the side airbag.

[0070] When the distal airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the front passenger seat, under the action of inertia, the front passenger seat occupant will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger seat occupant. While protecting the front passenger seat occupant, it is also necessary to reduce the squeezing of the main driver's seat when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the main driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the distal airbag detonation on the occupants.

[0071] Combined with the first aspect, Figure 2 As shown, in the eighth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the front passenger side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the front passenger riding condition includes:

[0072] S201. If the side collision position is on the passenger side and it is determined based on the collision parameters that the remote airbag deployment parameter threshold is reached, the remote airbag and the side airbag are controlled to be deployed simultaneously.

[0073] When the distal airbag of the side-impact vehicle is only set on the passenger side, the side impact position is on the passenger side, and the threshold of the distal airbag detonation parameter is reached according to the collision parameters, the driver of the main driving seat will quickly fall to the passenger side under the action of inertia. In order to protect the head of the main driving seat occupant, the distal airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the passenger side, the distal airbag and the side airbag are controlled to be detonated at the same time.

[0074] Combined with the first aspect, Figure 5 As shown, in the ninth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the front passenger side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the front passenger riding condition includes:

[0075] S201. If the side collision position is on the main driver's side, and it is judged based on the collision parameters that the remote airbag deployment parameter threshold is reached, and there is someone sitting on the front passenger seat, the remote airbag and the side airbag are controlled to be deployed simultaneously.

[0076] When the distal airbag of a side-impact vehicle is only set on the co-pilot side, the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the co-pilot seat, the co-pilot occupant will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the co-pilot occupant. The distal airbag is only set on the co-pilot side, and its detonation will not affect the main driver's occupant. Therefore, controlling the distal airbag to be set only on the co-pilot side can better protect the co-pilot occupant.

[0077] Combined with the first aspect, Figure 3 As shown, in the tenth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only arranged on the passenger side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the passenger riding condition includes:

[0078] S201. If the side collision position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger seat, the remote airbag is controlled not to be deployed.

[0079] When the distal airbag of a side-impact vehicle is only set on the co-pilot side, the side impact position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is no one in the co-pilot seat, since there is no occupant in the co-pilot seat and the main driver's occupant will not fall towards the co-pilot seat, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to detonate the distal airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0080] Combined with the first aspect, Figure 2 As shown, in the eleventh embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the main driver's side and the front passenger's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the front passenger's riding condition includes:

[0081] S201. If the side collision position is on the passenger side and it is determined based on the collision parameters that the remote airbag deployment parameter threshold is reached, the remote airbag and the side airbag are controlled to be deployed simultaneously.

[0082] When the remote airbags of the side-impact vehicle are set on both the main driver's side and the front passenger's side, and the side impact position is on the front passenger's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, the driver of the main driver's seat will quickly fall to the front passenger's side under the action of inertia. In order to protect the head of the main driver's seat, the remote airbag and the side airbag are controlled to be detonated at the same time, so that when a side impact occurs on the side away from the driver, the driver's head can be supported in time, the driver's head displacement can be reduced, and the injury to the driver's neck can be reduced. That is, regardless of whether there is someone on the front passenger's seat, the remote airbag and the side airbag are controlled to be detonated at the same time.

[0083] Combined with the first aspect, Figure 3 As shown, in the twelfth embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the main driver's side and the front passenger's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the front passenger's riding condition includes:

[0084] S201. If the side collision position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger seat, the remote airbag is controlled not to be deployed.

[0085] When the remote airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the driver's seat occupants will not fall towards the front passenger seat, the side airbags are sufficient to provide protection for the driver. Therefore, there is no need to detonate the remote airbag, and the driver can also be protected, while reducing the use of side airbags and reducing costs.

[0086] Combined with the first aspect, Figure 4 As shown, in the thirteenth embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the main driver's side and the co-driver's side, the strategy for determining the remote airbag detonation according to the side impact position, collision parameters and the co-driver's riding condition includes:

[0087] S201. If the side collision position is on the main driver's side, and it is judged based on the collision parameters that the remote airbag deployment parameter threshold is reached, and there is someone sitting on the front passenger seat, the remote airbag is controlled to deploy after the side airbag.

[0088] When the distal airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger side, under the action of inertia, the front passenger seat occupant will quickly fall to the driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger seat occupant. While protecting the front passenger, it is also necessary to reduce the squeezing of the driver when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the distal airbag detonation on the occupants.

[0089] In a second aspect, the present application provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application are implemented. The computer-readable storage medium has all the technical solutions of the remote airbag ignition method in a side collision, and thus has all the beneficial effects of the remote airbag ignition method in a side collision, which will not be described one by one in this application.

[0090] In a third aspect, the present application provides a computer program product, including a computer program, which, when executed by a processor, implements the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application. The computer program product has all the technical solutions of the remote airbag ignition method in a side collision, and thus has all the beneficial effects of the remote airbag ignition method in a side collision, which will not be described in detail in this application.

[0091] Fourthly, Figure 6 As shown, the present application provides a remote airbag ignition device in a side collision, comprising:

[0092] An acquisition unit, used to acquire a side collision position and collision parameters;

[0093] A control unit, used to determine the detonation strategy of the remote airbag according to the side impact position, collision parameters and the passenger seat condition;

[0094] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side impact locations and / or different passenger seat conditions.

[0095] In summary, whether to deploy the remote airbag is determined based on the side impact position, collision parameters and the passenger's riding conditions. In other words, the remote airbag and the side airbag are not controlled to deploy simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on the safety of the occupants.
